Our Leprechaun is a 2012. The layout is great for us, and the Chevy chassis has been problem free. However, the build quality of the coach is not very good. We've had plumbing leaks due to a screw run through a pipe during construction, leaks due to cheap connectors on the pex pipes, and roof leaks due to no caulking or gaskets on the marker lights. We still have one roof leak we haven't been able to track down. It feels like Coachmen used the cheapest parts, and the cheapest engineering they could.
This is by far not our first RV, nor is it our first Coachmen. It will be our last.
I agree completely with what Grumpy said.
In our Leprechaun (different model and different year) there is a wooden grill at the base of the kitchen cabinets. Above the grill is a sticker that reads "Low Point Drains". The three hoses that Grumpy talked about and their valves are behind that grill. The blue one is the fresh water tank drain in ours. The fresh tank is under the fridge, right next to this grill.
Don't know if this will help in your search.
We have a couple of these Rubbermaid plastic stools.
They stack together so they are easy to store and we use them for foot stools, side tables, whatever.
When its raining and we need to use an extension cord for the MH, I put the cord connection on one stool, and stack another stool on top. The bottom stool keeps the connection out of the puddles, and the top stool covers the plug from the rain.
